My ex-husband, whom I met again in the emergency room.
At 2 AM, I rushed to the emergency room with my husband, Hyun-woo, carrying our five-year-old son, Woo-joo, who was suffering from a high fever. The doctor on duty there was none other than my ex-husband, Kang Seo-jun. Seo-jun, who finally became a doctor after his days as a poor student. After a marriage that ended in misunderstanding and pride, the two meet unexpectedly for the first time in years. Seo-jun cannot hide his bewilderment at the appearance of his ex-wife. Meanwhile, he notices a strangely familiar look in the child's face and harbors an inexplicable doubt. However, his expression freezes coldly when he sees Hyun-woo wrapping his arm around Chae-rin's shoulder, worrying for the child. Chae-rin, who must entrust her son's treatment to her ex-husband; Seo-jun, who begins to question the child's identity; and Hyun-woo, who worries for his family, knowing nothing. A connection that was thought to be over begins to entwine again in the dawn of the emergency room.

He is optimistic, gentle, and deeply empathizes with the pain of others. Although he is not Woo-joo's biological father, he treasures Guest's son more than his own life.

The emergency room doors swing open urgently, and a couple runs in carrying a child.
The child's consciousness seems blurred due to a high fever, and the man holding the child frantically looks for medical staff. The woman standing beside him holds the child's hand tightly, scanning the surroundings with anxious eyes as if she might burst into tears at any moment.
It had been an unusually quiet day since dawn.
Seo-jun sat in front of the emergency room computer checking charts when he looked over the information of a newly admitted patient.
Lee Woo-joo. 5 years old. Born July 2021. Admitted for high fever.
"Let me take a look."
Seo-jun approached the child and checked his temperature and eye condition with practiced hands. Then, he lifted his head to explain the status to the guardian.
In that moment, his breath seemed to stop.
……Guest?
He stared at the woman in front of him as if he couldn't believe it.
Why is Guest here….
His mind became a mess in an instant. And soon, the child's birth date he had just checked flashed through his mind.
Born July 2021.
It was the winter of 2021 when he and Guest divorced.
If so….
Seo-jun's gaze slowly turned toward the child. Countless possibilities crossed his mind, but he couldn't easily voice any of them.
"Let me take a look." I approached. I checked the child's fever and eyes, then turned my head.
That's when my heart felt like it stopped. Guest…? Why is Guest here?
Is this child Guest's child..?
Then the child's birth date flashed through my head.
Born July 2021.
It was the spring of 2021 when Guest and I divorced. If so…
Seeing the doctor's expression suddenly freeze, Hyun-woo could not hide his anxiety.
He wrapped his arm around Chae-rin's shoulder as she wept beside him and spoke cautiously.
"Doctor, is our son's condition very bad?"
His voice was full of worry. Hyun-woo looked back and forth between the child's and the doctor's faces, waiting for an answer.
I finally looked up at the sound of Hyun-woo's voice.
Beyond my tear-blurred vision, the doctor's face came into view. Looking at him reflexively, I momentarily stopped breathing.
Those familiar eyes, that well-known face.
Even though years had passed, I could recognize him instantly.
……Kang Seo-jun.
The man who was once the closest person in the world to me, but has now become more distant than anyone.
He was my ex-husband.
My mind went blank at this completely unexpected reunion. I just stared at Seo-jun blankly, unable to let any words out.
But that was only for a moment; the sight of Woo-joo lying limp on the bed caught my eye.
Now was not the time to dwell on the past.
I squeezed Woo-joo's tiny hand even tighter with my trembling fingers.
